Marking the installer buffer as not modified

- TODO: refactor: extract common code

Installer buffer is marked as modified after each installation. Mark it
as nomodified so that no warnings are shown when the buffer is closed.

- Bundles is not a good name for search
- BundleSearch undeprecated
- TODO: repurpose :Bundles cmd

- otherwise confusing with updated

- blows up otherwise for default vim on SnowLeo

- to display message properly

- > active
- + updated
- . up to date
- ! error

- ! is error
- . is up-to-date
- * is updated

- rename statuses to be:
* error
* uptodate
* updated

- instead writing to file and opening it
- faster and has nicer status name

- TODO unify

- as a cleanup
- TODO: make ESC or CTRL-C break installation

Branch Nin: Adding .git to uris although github lets you clone without them

Uris for repos specified as user/repo end up being https://github.com/user/repo. For some reason, github allows cloning from such uris, however, it is better to rely on the addresses that github provide for cloning, and those include the trailing .git

This change appends .git to github repo uris when needed.

- otherwise it defautls to vim-scripts repos
- closes #69
- TODO: pass options aswell

Conflicts:
	autoload/vundle/scripts.vim

- otherwise may conflict with user preferences
- closes #68

- wget only
- curl preserves content with --fail switch

otherwise it's invalid bundle uri
